I also use VS2005 Pro.

Ever since I moved on from VC6 earlier this year, I've need to recompile
adns due, I presume, to it being linked with the VC6 CRT.  As a note,
you have to open and convert the older .dsw file to a newer VS .sln file
and then compile it.

This is similar to the issue with zlib.
